UNITED STATES HENRY K. KISO, OF NEW YORK, N. Y.

STRIKING-LINE.

Specification of Letters Patent.

Patented July 1 1 19 1 1.

Application filed October 26, 1910. Serial No. 589,154.

To all whom it may concern:

Be it known that I, HENRY K. Kiso, a subject of the King of Japan. and aresident of the city of New York. borough of Manhattan, in the countyand State of New York. have invented a new and Improved StrikingLine, ofwhich the following is a full, clear, and exact description.

My invention relates to striking lines used by carpenters. bricklayers,and various other artisans, for the purpose of marking straight linesupon rough or irregular surfaces.

My invention comprehends a disk-like casing in which is revolublymounted a drum and upon this drum the line is wound. The unwinding ofthe line turns the drum in one direction, the drum being retracted by aspring. The casing is provided with a sector-like opening and fittinginto this opening is a hollow door through which the line is drawn, anddisposed within the hollow door isthe inking apparatus.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective showing my device ready for use. the linebeing partially unwound: Fig. 2 is a substantially central verticalsection through the device, this sec tion being in a plane parallel withthe general plane of the casing; Fig. 3 is a cross section through thecasing and parts contained within it; and Fig. 4 is a detail showing thedrum and ratchet for holding the latter.

A casing 5 having generally the form of a hollow disk is provided with asector shaped slot 6. A hollow door 7 is connected with the casing 5 byaid of a hinge 8 and is of the form indicated in Fig. 1. The door 7 isprovided with a tongue 9 integral with it, the casing being providedwith parallel portions 10 between which is a slot for receiving thetongue 9. The tongue 9 is provided with a hole 11 through which a screw12 may be inserted so as to hold the door 7 closed. This screw isprovided with a thumb piece 12 whereby it may be more readily handled.

The door 7 is provided with an inner wall 14, the general outline ofwhich approximates in form that of the slot 6. The wall 14 is providedwith an eye 15. Mounted detachably within the door 7 and restingdirectly upon the wall 14 is a pad 16 of felt, sponge or other absorbentmaterial capable of holding by capillarity a quantity of fluid ink. Aroller 17 having generally the form of a double cone is revolublymounted upon a loop 18 of spring wire. This loop is provided withportions 18 which engage the inner surface of the door 7. The loop 18 ismounted in bearings 19 secured upon the inner surface of the door 7. Theloop 18 is so constructed and arranged that it constantly presses theroller 17 toward the pad 16.

At 20 is a line having generally the form of a cord. This line is woundupon a drum 21. Inside of this drum is a spiral spring 22. the inner endof this spring being secured to a sleeve integral with the casing 5 andforming a. bearing corresponding in approximate position with thecentral geometrical axis of the casing. The sleeve 23 is provided withtwo portions 24 separated by slots, and extending through these slots isa pawl 26. The drum 21 is further provided with a depression 21", thebottom of which is struck up to form ratchet teeth 25 which engage thepawl 26. This pawl is provided with a stem 27 and encircling the latteris a. spiral spring 28 for which a housing 29 is provided upon thecasing 5. The screw 12 is connected with the outer or free end of theline, the inner end of the latter being secured to the drum 21 and thebulk of the line being wound upon the drum as shown at 20. The line 20is threaded between the roller 17 and the pad 16 and extends out throughthe hole 13.

The operation of my device is as follows: Suppose the parts are in theirnormal posi tions as indicated in Fig. 2. and that the operator wishesto use the striking line. He grasps the thumb piece '12 and by its aidturns the screw 12 which thus becomes disengaged from the door 7 andeasing 5. The operator next pulls the screw away from the casing in adirection toward the left according to Figs. 1 and 2, thus drawing out aportion of the line 20. The line in traveling outward is pressed againstthe pad 16 by the roller 17 and is thus charged with ink. The screw 12is next pressed into the surface to be marked and the portion of theline outside of the casing is rendered taut by the op erator pulling thecasing backward for this purpose.

The operator next grasps the center of the exposed portion of the line,and drawing it away from the surface to be marked he releases it. Theline strikes the surface, leaving an ink mark. The operator now pressesupon the stem 27 and by causing the disengagement of the pawl 26 fromthe ratchet teeth 25 allows the drum 21 to turn back into its normalposition. This it does under control of the spring 22, thereby drawingthe slack line back into the casing. The screw is next inserted in thehole 11 so as to hold the door 7 rigid relatively to the casing. Thescrew thus serves the double purpose of normally holding the door closedand also of anchoring one end of the striking line when the line is tobe used.

I do not limit myself to any particular shape for any part shown.Neither do I limit myself to any particular purpose for which thestriking line is used.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. The combination of a casing provided with an opening, a doorconnected with said casing and adapted to open and close said opening, apad connected with said door and adapted to hold ink, a drum revolublymounted within said casing, and a line partially wound upon said drumand engaging said pad, said line extending outward from said door, and amember connected with said line for the double purpose of normallyholding said door closed and ot' temporarily anchoring the outer or freeend of said line.

2. A casing provided with an opening, a door mounted upon said casingand adapted to swing so as to close said opening, said door beinghollow, an ink pad carried within said door, a drum revolubly mountedwithin said casing, a line partially wound upon said drum and extendingthrough said door, said line engaging said pad within said casing, and afastening member connected with said line and provided with means fornormally holding said door closed.

The combination of a casing provided with an opening, a hollow doormounted upon said casing and adapted to close said opening, an ink padmounted within said door, a roller mounted within said door and adaptedto press upon said ink pad, a drum mounted within said casing. a linepartially wound upon said drum and extending through said hollow door,said line engaging said ink pad and also engaging said roller, and afastening member connected with the end of said line.

4. The combination of a casing having generally a disk-like form and.provided with a slot, :1 door connected with said casing and havinggenerally the same conformity as said slot so as to fill the latter,said door being hollow and provided with holes, an ink pad disposedwithin said door, a drum revolubly mounted within said casing, a linecarried by said drum and extending through said holes in said door, andmeans for forcing said line against said pad while said door is closed.

5. A casing provided with an opening, a door mounted upon said casingand adapted to swing so as to close said opening, said door being hollowand provided with holes extending through it, an ink pad carried withinsaid door, a drum revolubly mounted within said casing and accessible tothe operator when said door is open, and a line partially wound uponsaid drum and extend ing through said holes in said door, said lineengaging said pad within said door.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
